Description

  The present invention relates to a file management method, system, and program. More specifically, the present invention relates to a file management method, system, and program capable of presenting a file related to the file to a file.

  In the process of software development, documents such as source code and specifications for the program are modified. When a modification such as changing the software is necessary, the developer specifies a file to be modified, and performs the modification on the file. However, as software development becomes larger, the number of files increases. Therefore, if correction is spread to a plurality of locations, it is difficult to quickly find a file to be corrected. In addition, there is a problem that a malfunction occurs due to omission of correction.

  In response to the above problem, Patent Document 1 describes a software configuration management device that can present a configuration management element related to a change to a worker when the configuration management element is changed. In Patent Document 1, a relation information storage means for storing a relation between software configuration management elements such as a developed program and design information is used. In Patent Document 1, when a configuration management element is changed, the configuration management element related to the changed configuration management element is specified based on the relationship information stored in the relationship information storage unit.

JP 2000-250742 A

  In Patent Document 1, information related to configuration management elements is obtained from a file that can be extracted from a “#include” declaration written on the source code. In addition to direct dependencies, inter-file dependencies include indirect dependencies whose dependencies cannot be determined simply by analyzing the source code. However, since the dependency relationships that can be extracted from the source code are limited directly, in Patent Document 1, when correction is necessary for a plurality of locations that are indirectly dependent, all the correction locations are searched. Have difficulty. In addition, since all the correction portions cannot be extracted, there is a possibility that a correction omission occurs.

  The present invention relates to a file management method, system, and program capable of presenting a file having no direct dependency as a related file.

  In order to achieve the above object, the file management system of the present invention receives file identification information of a file to be processed, and sets the file identification information of a plurality of files whose difference in creation time or modification time is within a predetermined time. Reference is made to a set file recording means for recording, and a file pairing means for checking a file paired with the file to be processed and presenting information of the paired file is provided.

  According to the file management method of the present invention, a file management device receives a file identification information of a file to be processed, and a file of a plurality of files whose difference in time when the file management device is created or changed is within a predetermined time. A pair file recording means for recording identification information as a pair, examining a file paired with the file to be processed, and presenting information of the file paired.

  The program of the present invention is a set file record for recording, as a set, a process for receiving file identification information of a file to be processed and a set of file identification information of a plurality of files whose difference between created or changed times is within a predetermined time. Means for checking a file paired with the file to be processed and executing a process of presenting information of the file paired.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a file management system according to a first embodiment of the present invention. The file management system includes a file management apparatus 100 and a set file recording unit 101. The file management apparatus 100 includes a file correction detection unit 102 and a file presentation unit 103. Each unit in the file management apparatus 100 can realize its function in hardware, and can also be realized by executing a predetermined program on a computer system. The program is provided by being recorded on a computer-readable recording medium such as a magnetic disk or a semiconductor memory. The function of each unit in the file management apparatus 100 can be realized in the computer by the computer reading the recording medium storing the program and operating according to the program.

  The group file recording unit 101 records the file names of a plurality of files whose difference between the created and changed times is within a predetermined time as a group. For example, when there is a file A and another file B is modified within a predetermined time T from the modification time of the file A, the set file recording unit 101 records the file A and the file B as a set. The predetermined time T does not always have to be constant, and may differ depending on the file. As the time when the file was created / changed (modified time), the time when the corrected file was saved in the storage device is used. Alternatively, when software development is managed using a version management system, the time when the file is registered (committed) in the version management system may be the corrected time.

  The file correction detection means 102 detects file correction. For example, when the file being modified (edited) is stored in the storage device, the file modification detection unit 102 detects the modification of the file. When a version management system is used, a file modification may be detected when the modification is committed to the version management system. A method for detecting file correction is not particularly limited. When the file correction detection unit 102 detects the correction of the file, the file correction detection unit 102 notifies the file presentation unit 103 of information on the corrected file (file identification information). The file presentation unit 103 refers to the group file recording unit 101 and examines a file recorded as the same group as the file corresponding to the received file identification information. The file presentation unit 103 presents information on a file paired with the correction file to the user.

  FIG. 2 shows a specific example of information recorded by the set file recording unit 101. In FIG. 2, the set file recording unit 101 records information on sets of files from set 1 to set 3. For example, an operator records information in the set file recording unit 101 as needed. Alternatively, the computer may record information in the set file recording unit 101 by periodically referring to a file update history or the like. Each set stores information for specifying a plurality of files whose created / changed time differences are within a predetermined time. A file name can be used as information for specifying a file. For example, in FIG. 2, the set 1 stores the file name of the file A and the file name of the file B. The information for specifying the file is not limited to the file name, and may be other information.

  Here, the set file recording unit 101 sets not only files created / changed within a predetermined time from the last modification time of the file, but also files created / changed within a predetermined time from the past modification time of the file. Remember as. A file created / changed within a predetermined time from the past modification time can be specified by using a file update history or the like. For example, when the file A is corrected and the file B is corrected within a predetermined time from the correction time, the set of the file A and the file B (set 1) is recorded in the set file recording means 101. Further, when file A has been modified before that and file C has been modified within a predetermined time from the modification time, the group of file A and file C (group 2) is stored in group file recording means 101. Record.

  FIG. 3 shows an operation procedure. When the file is corrected (step A1), the file correction detection unit 102 detects the correction of the file (step A2). The file correction detection unit 102 notifies the file presentation unit 103 of the file identification information of the detected file (step A3). At this time, the file identification information notified to the file presentation unit 103 by the file correction detection unit 102 includes information to the extent that the file presentation unit 103 can acquire a paired file from the group file recording unit 101. For example, when the file A is created / changed in step A1, the file correction detection means 102 detects the correction of the file A in step A2, and in step A3, the file identification information of the file A is sent to the file presentation means 103. Notice.

  When the file presentation unit 103 receives the notification of the correction file from the file correction detection unit 102, the file presentation unit 103 searches for the set including the notified file with reference to the set file recording unit 101, and the file that forms a set with the notified file Is extracted (step A4). For example, when the file presentation unit 103 receives the file identification information of the file A from the file correction detection unit 102, the file presentation unit 103 refers to the group file recording unit 101 and searches for the group in which the file A is recorded. The file presentation unit 103 extracts the file recorded together with the file A in the set file recording unit 101 as a set file. Specifically, in the example of FIG. 2, the file B (set 1) and the file C (set 2) recorded together with the file A are extracted.

  The file presentation unit 103 determines whether or not the file has been extracted in step A4 (step A5). When one or more files can be extracted in step A4, the file presentation means 103 presents the extracted file to the user (step A6). For example, when the file B and the file C are acquired as a file to be paired with the file A at step A4, the file-to-file presentation unit 103 presents the file B and the file C to the user at step A6. If the paired file cannot be acquired in step A4, the process is terminated as it is.

  For example, consider a case where a file whose difference in time when a created / changed file is stored in a storage device is within a predetermined time is presented as a paired file. In the set file recording means 101, files having a difference in storage time within a predetermined time are recorded as a set. Developers modify files in units that are semantically coherent to changes required in the software. For example, when it is necessary to correct a plurality of defects, it is more efficient to correct the defects one by one than to correct a plurality of defects at the same time. Therefore, it is highly probable that a file group with a modified and saved time is close to the same change. From this, it can be said that the group file recording means 101 records a group of files to be corrected simultaneously for each change as a group. By using this set, it is possible to present to the user a file that is likely to be modified at the same time when the file is subsequently modified.

  Also, consider a case where a file whose difference in time when a created / changed file is committed to the version management system is within a predetermined time is presented as a paired file. In the set file recording means 101, files whose difference in time committed to the version management system is within a predetermined time are recorded as a set. One of the advantages of using version management for software management is to record past changes, for example, when software is incomplete at a certain point in time, identifying the correction that caused deficiencies by going back in the history. And the ability to return the software to a normal state. To take advantage of this advantage, registration to version control should be done in semantically unity units. Therefore, the file group registered in the version management system at the same time is highly likely to have been corrected for the same change. From this, it can be said that, similarly to the above, the set file recording means 101 records a group of files to be corrected simultaneously for each change. By using this set, it is possible to present to the user a file that is likely to be modified at the same time when the file is subsequently modified.

  The file management system of this embodiment has a file presentation unit 103 as a minimum configuration. The file presentation unit 103 refers to the group file recording unit 101 that records a file whose creation / change time is within a predetermined time as a group, examines the file paired with the file to be processed, and forms the group file To the user. In this way, a file created / changed at a time close to the time when the file to be processed was created / changed in the past can be presented to the user. In the method of analyzing the file and obtaining the dependency relationship such as Patent Document 1, it is impossible to present a file in which the dependency relationship cannot be extracted from the file. In this embodiment, since the file created / changed at a time close to the time when the file to be processed is created / changed is presented to the user, the file is indirectly related to the file to be processed whose dependency is not known. Files that depend on can also be presented to the user as related files.

  In the present embodiment, the file correction detection unit 102 is used, and the file presentation unit 103 presents a file paired with the correction file, with the correction file detected by the file correction detection unit 102 as a processing target. A file that is close to the modified file and created / changed is a file that is highly likely to depend directly or indirectly on the modified file. Therefore, it is a file that is likely to be modified after the modified file is modified. It can be said that there is. In the present embodiment, when a certain file is modified, a file that directly or indirectly depends on the modified file is presented to the user. By doing in this way, the file which should be corrected simultaneously with a correction file can be shown to a user, and the effect which can reduce the correction omission of the file in a dependence relationship can be anticipated.

  FIG. 4 shows a file management system according to the second embodiment of the present invention. The file management system according to the present embodiment is different from the file management system according to the first embodiment in that the file management apparatus 100a includes a file reception unit 104 instead of the file correction detection unit 102 (FIG. 1). The set file recording unit 101 and the file presentation unit 103 are the same as those in the first embodiment. That is, the set file recording unit 101 records file identification information of a plurality of files having a difference in time created or changed within a predetermined time as a set. The file presentation unit 103 refers to the group file recording unit 101, examines a file paired with the processing target file, and presents information on the paired file.

  The file receiving unit 104 receives a file specification from the outside. The user can designate an arbitrary file to the file receiving unit 104 as a designated file. For example, prior to file correction, the user designates a file to be corrected to the file receiving means 104. When receiving the designation of the file, the file receiving unit 104 notifies the file presentation unit 103 of the file identification information of the designated file. The file presentation unit 103 refers to the group file recording unit 101 to check the file paired with the file corresponding to the file identification information notified from the file reception unit 104, and informs the user of the information of the group file. Present.

  FIG. 5 shows an operation procedure of the file management system of the second embodiment. A software developer or the like designates a file to the file receiving means 104 (step B1). The file receiving unit 104 notifies the file presentation unit 103 of the file identification information of the designated file (step B2). Subsequent operations are the same as steps A4 to A6 in FIG. That is, the file presentation unit 103 refers to the group file recording unit 101 in step A4, extracts a file paired with the designated file, and determines whether a group file exists in step A5. When there is a file to be paired, the file presentation unit 103 presents the file to be paired with the designated file to the user in step A6.

  In the present embodiment, the file receiving unit 104 receives a file designation and notifies the file presentation unit 103 of file identification information of the designated file. The file presenting means 103 extracts the information of the file paired with the designated file from the set file recording means 101 using the designated file notified from the file accepting means 104 as a processing target file, and presents it to the user. In this embodiment, the user can specify an arbitrary file at an arbitrary time. Therefore, it is possible to present to the user a file having a relationship dependent on an arbitrary file at an arbitrary time regardless of whether or not the file is modified. The user can use the presented information to assist in understanding the software. The point which can present the file which has the relation which depends indirectly on a user is the same as that of a 1st embodiment.

  FIG. 6 shows a file management system according to the third embodiment of the present invention. The file management system according to the present embodiment is different from the file management system according to the first embodiment in that the file management apparatus 100b includes a set file registration unit 105 in addition to the file correction detection unit 102 and the file presentation unit 103. To do. The group file recording unit 101, the file correction detection unit 102, and the file presentation unit 103 are the same as those in the first embodiment. That is, the set file recording unit 101 records file identification information of a plurality of files having a difference in time created or changed within a predetermined time as a set. The file correction detection means 102 detects file correction. The file presentation unit 103 refers to the group file recording unit 101, examines the file paired with the correction file, and presents information on the group file.

  The set file registration unit 105 receives the file identification information of the correction file from the file correction detection unit 102 and receives the file identification information of the file paired with the correction file from the file presentation unit 103. The set file registration unit 105 determines whether there is a corrected file among the files paired with the correction file. The set file registration unit 105 records the file identification information of the correction file and the file identification information of the file that has been corrected among the files that are paired with the correction file, in the set file recording unit 101.

  FIG. 7 shows an operation procedure of the file management system according to the third embodiment. The operations from the modification of the file to the presentation of the file paired with the modified file are the same as in the first embodiment. That is, when the file is corrected in step A1, the file correction detecting unit 102 detects the correction of the file in step A2, and notifies the file presentation unit 103 of the file identification information of the corrected file in step A3. The file presentation unit 103 refers to the group file recording unit 101 in step A4, extracts a file paired with the modified file, and determines whether a group file exists in step A5. If there is a file to be paired, the file presentation means 103 presents the file to be paired with the correction file to the user in step A6.

  The set file registration unit 105 receives the file identification information of the file whose correction is detected in Step A2 from the file correction detection unit 102. Further, the set file registration unit 105 receives the file identification information of the file presented to the user in Step A6, that is, the file paired with the correction file extracted in Step A4, from the file presentation unit 103. The user appropriately selects a file from the presented files and corrects the file. When the user corrects at least one of the presented files accompanying the file corrected in step A1, the set file registration means 105, the file identification information of the file corrected in step A1, and the user The file identification information of the file actually corrected among the files presented in the above is registered as a set in the set file recording means 101 (step C7).

  In the present embodiment, the set file registration unit 105 sets the file identification information of the corrected file and the file identification information of the corrected file among the files presented by the file presentation unit 103 as a set. Register in the recording means 101. By doing so, it is possible to present to the user a file to be paired with the correction file by using the information recorded by the paired file registration means 105 from the next time. In addition, when the file is modified, the information recorded in the set file recording unit 101 can be updated, and the information recorded in the set file recording unit 101 is periodically updated separately using an editing history or the like. The processing to do becomes unnecessary. Other effects are the same as those of the first embodiment.

  Hereinafter, description will be made using examples. The file is a source file described in C language. Subversion is used as a version management system. The group file recording unit 101 records a group of files that have been simultaneously committed to Subversion as a group of files within a certain period of time difference between creation / change times.

  FIG. 8 shows a software development environment. The client 801 includes a keyboard that receives input from the developer, a display that displays editing status and various information, and the like. A developer uses the client 801 to develop software. In the client 801, the svn wrapper program 802 is operating. The svn wrapper program 802 includes a program for realizing the function of the file management apparatus in the client 801.

  Subversion 812 is operating on the server 811. Files under development are managed by Subversion 812. The server 811 and the client 801 are connected via a network 821.

  9A to 9C show program source files. 9A shows the file A (file name a.c), (b) shows the file B (file name b.c), and (c) shows the file C (file name c.c). File A has a description for calling the functions defined in file B and file C through the function pointer. Versions of these files A to C are managed by Subversion 812. The developers of file B and file C are the same, and the developer commits these two files to Subversion 812 at the same time.

  Assume that a developer modifies file A and file B in accordance with a change in the data structure that is the return value of the function, and commits file A and file B using the svn wrapper program 802. When the svn wrapper program 802 receives the file A and the file B, the svn wrapper program 802 obtains a file C that has been committed simultaneously with the file B from the Subversion 812 in the past. The svn wrapper program 802 displays the file C on the display of the client 801 and informs the developer of the existence of the file C.

  In source code analysis using a call graph or the like, the function assigned to the function pointer cannot be specified accurately. Therefore, in the source code analysis, it is impossible to extract the function in the file C that is substituted for the function pointer of the file A, and it is impossible to grasp that the file A and the file C are in a dependency relationship. Further, there is no dependency between file B and file C. Therefore, in the method of analyzing the source code, when the file A and the file B are corrected, the file C to be corrected cannot be presented to the developer at the same time.

  In this embodiment, file B and file C are simultaneously committed to Subversion 812, and the set of file B and file C is recorded in the set file recording unit 101. When the developer corrects the file A and the file B in accordance with the data structure change of the return value of the function, the file presentation means 103 (FIG. 1) sends the file C committed at the same time as the file B to the developer. Present. For the file C presented by the developer, it is possible to prevent omission of file correction by changing the data structure of the return value of the function.

  The above embodiments can be used in appropriate combination. For example, the file management apparatus 100a of FIG. 4 may further include a file correction detection unit 102. In this case, the file-to-file presentation unit 103 presents a pair of files when the file modification detection unit 102 detects file modification and when the file reception unit 104 receives a file designation. In the third embodiment, among the files presented by the set file registration unit 105 to the user, the modified file is recorded in the set file recording unit 101 as a set. In addition to this, the set file is presented to the user. Files modified other than files may be recorded in the set file recording unit 101.

  Although the present invention has been described based on the preferred embodiment, the file management method, system, and program of the present invention are not limited to the above embodiment, and various configurations are possible from the configuration of the above embodiment. Those modified and changed as described above are also included in the scope of the present invention.
